Higher voltage than a fully charge battery can supply, when applied to the
battery terminals drives the chemical reaction and changes it from releasing electrons to storing electrons but does not reverse
the current as most dumb engineers claim.
Oh? So how come the little arrow marked "I" (current) has changed direction between the third and fourth pictures?
Duh! That is an EXTERNAL circuit. Note how there is never an arrow
shown inside the battery - only chemical reactions shown because
there is no internal circuit.
